Download speed

I was regularly getting around 600mb download speeds from my wired connected PC. However, my download speed tests are now topping out at around 300mb. It's not my PC as I have run speed tests with a second PC and my laptop all wired directly into my hub with a similar result
Looking at my router status stats I appear to have some issues. Can anybody help?

Re: Download speed

Downstream channels 6 & 7 have a lot of Post RS errors and the upstream power levels are at the top of the recommended range. These things are not ideal and could result in slower speeds.

You will probably need a technician to visit and adjust the upstream power levels and investigate the cause of the Post RS errors.

You can try to book a visit by calling 150 from a VM landline or 0345 454 1111 from any other phone.  

If you can't get through on the phone then VM are recommending you send a text to 07533 051809 describing the issue and you should get a response, but it may take a day or two at present. This is a text only service, it does not support voice calls.  
https://community.virginmedia.com/t5/Digital-life/When-and-how-to-use-our-messaging-service/ba-p/425... 


Or you can wait for one of the VM forum team to get to this thread, which usually also takes a few days.

Re: Download speed

Hi there @sjw444

 

Welcome to our Community and thanks so much for your first post - I was sorry to understand that you've been having some issues with your broadband recently. 

 

After locating your account from your Forum information, we can see that it's been around 3 days since your Hub was rebooted; we have no errors showing and all your signal levels are where we would expect - however, we have identified some network instability which we believe will only be short term.

 

In the meantime, please do check your connections at home and make sure they're finger tight. 

 

Pop back when you can if you're still having issues in 24/48 hours and we'll go through more checks with you. 

 

Cheers

Katie - Forum Team

Re: Download speed

Hi @sjw444,

 

I'm sorry that you're still experiencing speed issues and I've had a look at your details and can see that everything looks fine and within range. Your upstream power, although it's not over the high parameters, looks like it's hitting the high range and with real time fluctuations, it may affect your speeds so I've arranged for an engineer visit to take a look. 

 

You may find the details via your online account where you can re-arrange it if necessary. Do pop back and let us know how it goes.

 

Thanks,

 

Lisa
